AUTOMOBILE SIGNAL.

Application filed March 7, 1921. Serial No. 459,125.

To all whom it may canoe/1%: I

Be it known that I, ERNEST J. HART, a citizen of the United States, residing at Rochester, in the county of Monroe, State of New York,

Signals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in signals and particularly to direction signals for automobiles.

One object of the invention is to provide an automobile signal which is simple in construction, easy and effective in its operation, and which can be manufactured at a low cost.

Another object is to provide a signal of the character named having novel means for lighting and extinguishing an electric lamp carried by the signal arm, so that the lamp will. only be burning at the time that the arm is in elevated or signaling position.

Other objects and advantages will be ap parent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a front elevation of the signal, applied to an automobile, the signal arm being in elevated or indicating position.

Figure 2 is a side elevation of the same.

Figure 3 is a vertical sectional view, just inside of the front wall or hinged cover of the casing, to show the arrangement of the parts within the casing, the arm being shown in full lines in its elevated position, and in dotted lines in its lowered position.

Referring particularly to the accompanying drawing, 10 represents a shallow casing which is secured to the left side of the front of the automobile 11. In the outer side of the casing there is formed a longitudinal opening 12, and in the bottom of the casing there is formed an elongated opening 13, the purpose of which will presently appear herein. Pivotally mounted in the casing and arranged to be swung into elevated or indicating position through the side opening 12, at times, and to extend downwardly through the opening 13, when in nonindicating position at times, is the signaling arm 14, aid arm having the semblance of an have invented certain new and -useful Improvements in Automobile the casing,

from the front, and

open hand formed on its outer end, and an opening 15 through the center of the palm thereof. Mounted on the palm of the hand by me-ansof the clamp 16, is an electric lamp 1?, the same being so arranged that it is in full view from the front of the automobile, and can be seen through the opening 15, from the rear of the automobile. Secured to the outer edge face of the arm 14 is one end of a cord 18, the same extending vertically in the casing and passing over a roller 19, and thence outwardly through an opening 20 in the upper portion of the inner edge of the casing, where said cord is provided with a hand grip 21, adapted to be grasped by the driver to pull the cord and cause the elevation of the arm through the side opening 12, into indicating position. hen, however, the cord is released, the arm will fall into depending position by gravity. Secured to and extending longitudinally of the inner end face of the arm 14 is a metallic bowed spring to which is connected one end of a wire 23, said wire extending outwardly along the arm 14: and being connected with the lamp 1.7. A second wire 23, coimected to the lamp, extends along the arm 14., rearwardly and out through an opening in the side of below the opening 20, as shown at: 24-. Below the opening 2 1, and secured to the inner face of the inner side wall of the casing, is a stationary contact which is adapted to be engaged by the outer end of the bowed spring 22, when the arm l-l raised into indicating position, for the purpose of closing the circuit through the lamp. A wire 26 is connected to this stationary contact 25, and extends out through the opening 24, together with the other wire 23, to a source of current, which might be the lighting system of the automobile, or in the absence thereof, to a number of dry cells, not shown.

From the above, it; will be readily seen that when the cord 18 is pulled the arm 141- will be raised into horizontal indicating posit-ion through the side opening 12. The spring 22 will contact with the stationary contact 25 to complete the circuit and light the lamp, whereby the lamp will be in full view of the drivers of vehicles approaching through the opening 15, by drivers approaching from the rear. When the cord 18 is released, and the arm permitted to swing down by gravity, the

spring will be moved away from the contact 25 so that the circuit will be broken and the lamp extinguished.

While I have shown the signal arm as operable by means of a cord I Wish it understood that the same may be operated by means of a chain Without departing from the spirit of the invention.

lVhat is claimed is:

An automobile direction signal including a substantially rectangular casing having its outer side partly open and its lower end entirely open, a signal arm pivotally mounted at its lnner lower corner in the casing and movable through the said partly open side and open end into and out of signaling position, a transverse Wall above the partly open side and having a vertical opening therein, a guide pulley mounted in the casing directly above said opening, and a cord secured to the intermediate portion of the upper outer edge of said arm and extending upwardly through said opening, around said guide pulley, and through an opening in the closed side of the casing.

In testimony whereof, I aflix my signature.

ERNEST J. HART.
